Abstract

Background: Serum uric acid level is regulated by gender, dietary habit, genetic predisposition, and renal function, and is associated with the development of renal and cardiovascular diseases. This study prospectively investigated the association between serum uric acid levels and mortality in a community-based population. Methods: Three thousand four hundred and eighty-seven subjects regardless of the antihyperuricemic medication (45 % male; mean age 62 years old) from the Takahata town in Japan participated in this study and were followed up for 8 years (median 7.5 years). We examined the association between serum uric acid levels at baseline and the all-cause and cardiovascular mortality, respectively, in this population. Results: One hundred seventy-nine subjects died during the follow-up period, with 49 deaths attributed to cardiovascular causes. Kaplan–Meier analysis revealed that the all-cause mortality was significantly higher along with the increase in serum uric acid levels at baseline among female (Log-rank P < 0.01), but not male subjects (P = 0.97). Cox-proportional hazard model analysis with adjustment for possible confounders including age, renal function, and comorbidities revealed that hyperuricemia (uric acid ≥7.0 mg/dL) was an independent risk factor for all-cause and cardiovascular mortality, respectively, in female [hazard ratio (HR) 5.92, 95 % confidence interval (CI) 2.10–14.6 for all-cause mortality, and HR 10.7, 95 % CI 1.76–50.2 for cardiovascular mortality], but not male subjects. Conclusion: Hyperuricemia was an independent risk for all-cause and cardiovascular mortality in female, but not among the male subjects in a community-based population.
